如何在 QT 上自动点击 QPushButton

Question

I am trying to auto click and refresh QTextBrowser. But can't figure it out how. My codes are below.

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    QPixmap pix_w ("/home/pi/Downloads/wifi.png");
    QPixmap pix_s ("/home/pi/Downloads/laser.png");
    QPixmap pix_m ("/home/pi/Downloads/main.png");
    ui->label->setPixmap(pix_w);
    ui->label_2->setPixmap(pix_s);
    ui->label_5->setPixmap(pix_m);
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::on_pushButton_clicked()
{
    QFile file("/home/pi/Desktop/test1.txt");
        if(!file.open(QIODevice::ReadOnly))
            QMessageBox::information(0,"info",file.errorString());

        QTextStream in(&file);

        ui->textBrowser->setText(in.readAll());
}

Answer 1

Once you have a pointer to your QPushButton, you can call click() on it; or if you'd like to see the button visually animate, as if the user had clicked on it (in addition to emitting its clicked() signal), you can call animateClick() on it instead.

插槽不是其他方法，您可以在同一个 MainWindows 类中调用它，它会执行与单击按钮相同的逻辑
